This paper proposes a new sliding mode observer (SMO) based anti-windup PI speed control strategy for Permanent Magnet Synchronous Motor (PMSM). A SMO is constructed to estimate the back-electromotive-force (EMF) signals robustly, and then the position and speed of a PMSM can be calculated according to the back-EMF equations. Based on the estimated position and speed of PMSM, four different anti-windup PI strategies are used and compared for speed control of PMSM, The simulation results show the superior control performance compared with conventional schemes.
